Hello!
I've build a simple robot. I wanted to make a line follower, and I followed the diagram here to make the motor controller (disregarding the other schematics):
http://www.diylive.net/index.php/2005/12/13/diy-line-following-robot2/
So I assembled the robot and set up some test code. Basically, turn right motor on for 5 seconds, the left motor on for 5 seconds and loop.
When I run it, the left motor turns on fine as it is supposed to. When it is supposed to switch the motors, it seems the right one does not turn on. Both motors have the same motor controller components, and I've hooked them up the same way.
When the right one is supposed to go on, I gently spin it in and it seems to start running. I guess there is some kind of problem with it starting to spin. When I spin it manually, it starts to work.
It cannot be the motors, I've changed the motor to a different one and hooked it up. Same problem.
Any ideas?
Omar
